Ok, at this point I have my sprite engine converted over to use the
new bitstream if it's available. I do notice now though that since
the boards vertical is running at 56Hz, although my LCD will sync to
it, it seems to give me a hitching type behavior on my LCD during
smooth motion that was not present when using the default loadout that
sync'd at 60Hz. Is there something I can do to compensate for the
refresh rate difference? I am waiting for the vsync, but I think the
vsync rate change is the problem in this case. There is no other
timing code in my simple application other than using the vsync. Any
ideas what might be going on? Jesse?
